Preston, the Vanisher + Delney, Streetwise Lookout + Sefris of the Hidden Ways + Viscera Seer + Undermountain Adventurer
How it works
- Complete a dungeon.
- Sefris' second ability triggers twice due to Delney.
- Resolve the first trigger, returning up to one other creature from your graveyard to the battlefield.
- Resolve the second trigger, returning Undermountain Adventurer from your graveyard onto the battlefield.
- When Undermountain Adventurer enters, it triggers once and Preston triggers twice due to Delney.
- Holding priority, activate Viscera Seer by sacrificing Undermountain Adventurer.
- Resolve a Preston trigger, creating a token copy of Undermountain Adventurer that is a 0/1 Illusion.
- When the Undermountain Adventurer token enters, it triggers twice due to Delney.
- Resolve the Undermountain Adventurer token triggers, venturing into Undercity twice.
- Resolve the second Preston trigger from step 5, creating a token copy of Undermountain Adventurer that is a 0/1 Illusion.
- Repeat steps 8 and 9 one additional time.
- Resolve the Undermountain Adventurer trigger from step 5, venturing into Undercity and completing Undercity.
- Repeat from step 2.
This brilliant loop hinges on Delney, Streetwise Lookout doubling the triggered abilities of your small creatures, turning a single dungeon completion via Sefris of the Hidden Ways into a cascading engine. When Sefris returns Undermountain Adventurer from your graveyard, Delney ensures both Preston, the Vanisher and the Adventurer's own entry triggers go wild, creating a flurry of Illusion token copies that aggressively venture through the Undercity. Viscera Seer acts as the vital outlet to sacrifice the original Undermountain Adventurer in response, letting the tokens take over the heavy lifting of repeating the entire process endlessly. By constantly completing dungeons on the fly, Sefris perpetually loops your fallen threats right back onto the battlefield to fuel the carnage.
